Add some new features

1. use Emacs Package systems to mange the plugins on Windows
2. use magit as emacs git interfaces
Set shortcut key C-x g to execute 'magit-status'
Modify the package system's install dir and move the original files into
lisps folder

The original path is ~/.emacs.d/elpa/
Now it's ~/emacsconfig/lisps/
